An English exotic car, features steering, suspensions, big block Harley Davidson engine with pushrods and rockers, gearbox and boot which opens.

I have been planning for a while to build a 3-wheel car. This exotic car is made by the British manufacturer Morgan. The big block Engine is a Harley Davidson’s Engine with pushrod system and rockers. Usually, the engine has two push-rods and two rockers by cylinder (inlet and exhaust valve). But on the lego version, I had only 3 stud-width available so I decided to put only one pushrod with rocker because of the room. I also decided to have visible moving part to be more expressive (real version doesn’t have visible pushrods or rockers). Then the drive-shaft goes to the gearbox ,which is an 4-speed gearbox based on #8880 modified version. The following ratios are : 1:1 1:2 1:3 1:6. Then, the drive-shaft goes to a bevel gear, and finally the main drive-chain.

Regarding the suspensions, the front suspensions are composed of double wishbones with hard shock-absorbers. The rear suspensions is a swinging arm with two soft shock-absorbers. Note that the center of rotation of the rear arm is not the center of rotation of the pinion-chain. The body was the most difficult part of this moc, because of this shape and the room. The first thing I have done is to design the hood. Then, I designed the right and left panel while trying to be homogeneous in the shape (discontinuity in alignment). To finish, I have made the rear shape and that was the most difficult part. All designed lines had to cross each other to be elegant, including the opening of the boot.

The interior shape has also received a lot of attention. I have managed the global shape by using flex parts all around the interior and by matching the panel with the flex (there was not much space to include gearbox, seats and interior). The shape is not perfectly accurate but the global shape and scale are respected. Also, the boot can be opened (in the correct direction) and the Hood can be removed as on real version.

Thank you very much for making these building instructions of the Morgan Supersport 1937.

If have build your model for my 75 year grandfather for his birthday in white, he used to own a creme one in the 1950’s.

I have mode some small changes with his model, a brown dashboard, gearbox and a chrome rollbar.
Also I changed the rear lights, I have made them the back (you used 2 liftarms at each side 1×5) I have changed 1 liftarm into a 1×3 and above 2 connectors 1×3 with 2 round holes and 1 x hole to place the rear lights (indicator and brake).

My grandfather is very happy with your model, and also on behalf of him, we thank you for this model.

First of all, I’d like to thank you a lot for sharing instructions for this wonderful model.
I just finished building the car and it’s really impressive and fascinating.

I just made some minor changes that, IMHO, make the model even better:
1 – I used chromed parts (custom) to build motor and radiator, the final effect is wonderful!
2 – I changed the technic connector and axles used to build the windscreen with a combination of windscreen 5×2x1-2/3 (part 6070) and Hinge cylinder + hinge Plate 1×2 to support it through the same axle (reduced to a 4 studs); the effect is awesome.
3 – I used 8420 disk brakes for front wheels, much more realistic.
4 – I used 2 Pins 3/4 (part 32002) between the side panels 1×5x11, to fix them better.
5 – I changed the two soft shock absorber used for rear wheel with two hard one, due two short movement range of rear axle.
The final model is really wonderful!
If you like it, I can send you pictures of it.

I really love your creations! I’m a novice lego builder and what I do is taking old lego parts to assemble a new model.

How do you design your creations? Do you design them using LDD and then buy the bricks online to join them together ?
There are like thousands types of bricks. How do you find the right ones? There are so many bricks in your models I’ve never seen in my life…
